2015 United Kingdom general election

The Fixed-term Parliaments Act 2011 led to the dissolution of the 55th Parliament on 30 March 2015 and the scheduling of the election on 7 May. There were local elections on the same day in all of England, with the exception of Greater London. No elections were scheduled to take place in Scotland, Wales, or Northern Ireland. All British, Irish, and Commonwealth citizens over the age of 18 and residing in the UK who were not in prison or a mental hospital or a fugitive on the date of the election were permitted to vote. In British general elections, voting takes place in all constituencies in the United Kingdom to elect Members of Parliament to the House of Commons, the lower house of Parliament in the UK. Each constituency elects one MP using the first-past-the-post voting system. If one party obtains a majority (326) of the 650 seats, then that party is entitled to form the government. If no party has a majority, then there is what is known as a hung parliament. In this case, the options for forming the Government are either a minority government (where one party governs alone despite not having the majority of the seats) or a coalition government (where one party governs alongside party in order to get a majority of seats). Although the Conservative Party planned for the number of constituencies to be reduced from 650 to 600, through the Sixth Periodic Review of Westminster constituencies under the Parliamentary Voting System and Constituencies Act 2011, the review of constituencies and reduction in seats was delayed by the Electoral Registration and Administration Act 2013. The next boundary review was set to take place in 2018, so the 2015 general election was contested using the same constituencies and boundaries as in 2010. Of the 650 constituencies, 533 were in England, 59 were in Scotland, 40 were in Wales and 18 were in Northern Ireland. In addition, the 2011 Act mandated a referendum in 2011 on changing from the first-past-the-post voting system to an alternative vote system for general elections. The Conservative–Liberal Democrat coalition government agreed to holding a referendum. The referendum was held in May 2011 and resulted in the retention of the existing voting system. Before the previous general election the Liberal Democrats had pledged to change the voting system, and the Labour Party had pledged to hold a referendum on any such change. The Government increased the amount of money that parties and candidates were allowed to spend on campaigning during the election by 23%, a move decided against the advice of the Electoral Commission. The election saw the first cap on spending by parties in individual constituencies during the 100 days before Parliament's dissolution on 30 March: £30,700, plus a per-voter allowance of 9p in county constituencies and 6p in borough seats. An additional voter allowance of more than £8,700 is available after the dissolution of Parliament. In total, parties spent £31.1m in the 2010 general election, of which the Conservative Party spent 53%, the Labour Party spent 25% and the Liberal Democrats 15%. This was also the first UK general election to use individual rather than household voter registration. ==Date of the election==

on 7 May 2015. An election is called following the dissolution of the Parliament of the United Kingdom. The 2015 general election was the first to be held under the provisions of the Fixed-term Parliaments Act 2011. Prior to this, the power to dissolve Parliament was a royal prerogative, exercised by the sovereign on the advice of the prime minister. Under the provisions of the Septennial Act 1715, as amended by the Parliament Act 1911, an election had to be announced on or before the fifth anniversary of the beginning of the previous parliament, barring exceptional circumstances. No sovereign had refused a request for dissolution since the beginning of the 20th century, and the practice had evolved that a prime minister would typically call a general election to be held at a tactically convenient time within the final two years of a Parliament's lifespan, to maximise the chance of an electoral victory for their party. Prior to the 2010 general election, Labour and the Liberal Democrats pledged to introduce fixed-term elections. As part of the Conservative–Liberal Democrat coalition agreement, the Cameron ministry agreed to support legislation for fixed-term Parliaments, with the date of the next general election being 7 May 2015. This resulted in the Fixed-term Parliaments Act 2011, which removed the prime minister's power to advise the monarch to call an early election. The Act only permits an early dissolution if Parliament votes for one by a two-thirds supermajority, or if a majority of MPs pass a vote of no confidence and no new government is subsequently formed within 14 days. However, the prime minister had the power, by order made by Statutory Instrument under section 1(5) of the Fixed-term Parliaments Act 2011, to fix the polling day to be up to two months later than 7 May 2015. Such a Statutory Instrument must be approved by each House of Parliament. Under section 14 of the Electoral Registration and Administration Act 2013, the Fixed-term Parliaments Act 2011 was amended to extend the period between the dissolution of Parliament and the following general election polling day from 17 to 25 working days. This had the effect of moving forward the date of the dissolution of the Parliament to 30 March 2015. Timetable The key dates were: ==MPs not standing for re-election==

While at the previous election there had been a record 149 MPs not standing for re-election, the 2015 election saw 89 MPs standing down. Out of these MPs, 37 were Conservatives, 37 were Labour, 10 were Liberal Democrats, 3 were Independents, 1 was Sinn Féin and 1 was Plaid Cymru. The highest-profile members of parliament leaving were: Gordon Brown, the former Prime Minister, and William Hague, the former Leader of the Conservative Party and Leader of the Opposition. Alongside Brown and Hague, 17 former cabinet ministers stood down at the election, including Stephen Dorrell, Jack Straw, Alistair Darling, David Blunkett, Sir Malcolm Rifkind and Dame Tessa Jowell. The highest-profile Liberal Democrat to stand down was their former leader Sir Menzies Campbell, while the longest-serving MP, Sir Peter Tapsell, also retired, having served as an MP continuously since 1966, or for 49 years. ==Contesting political parties and candidates==

showing opening hours of polling stations, including the advice that people queuing outside polling stations at 10.00 pm "will be entitled to apply for a ballot paper". Overview On 9 April 2015, the deadline for standing for the general election, there were 464 political parties registered with the Electoral Commission. Candidates who did not belong to a party were either labelled as an Independent or not labelled at all. The Conservative Party and the Labour Party had been the two biggest parties since 1922. Every prime minister to serve since 1935 had been the leader of the Conservatives or Labour. Opinion polls had predicted that the two parties would receive a combined total of anywhere between 65% and 75% of votes, and would receive anywhere between 80% and 85% of the seats; and that, as such, the leader of one of the two parties would become the Prime Minister (David Cameron of the Conservatives or Ed Miliband of Labour) after the election. The Liberal Democrats had been the third largest party in the UK for many years; but as described by various political commentators, other parties had risen relative to the Liberal Democrats since the 2010 election. In order to emphasise this, The Economist stated that "the familiar three-party system of the Tories, Labour, and the Lib Dems appears to be breaking down with the rise of UKIP, the Greens and the SNP." Ofcom ruled that the major parties in Great Britain were the Conservatives, Labour, the Liberal Democrats and UKIP, the SNP a major party in Scotland, and Plaid Cymru a major party in Wales. The BBC's guidelines were similar but removed UKIP from their list of major parties, and instead stated that UKIP should be given "appropriate levels of coverage in output to which the largest parties contribute and, on some occasions, similar levels of coverage". Seven parties participated in the election leadership debates: Conservative, Labour, Liberal Democrat, UKIP, SNP, PC and Green. Northern Ireland's political parties were not included in any debates, despite the DUP, a party based in Northern Ireland, being the fourth largest party in the UK going into the election. National stood for a second term in office. was leader of the opposition and leader of the Labour Party after winning a leadership election against his brother David Miliband. and the Liberal Democrats showed a great fall in the polls after entering a coalition government with the Conservatives. leader Nigel Farage stood in the South Thanet constituency. was the fifth First Minister of Scotland and the leader of the Scottish National Party, in office since 2014. She is the first woman to hold either position. , leader of the Green Party of England and Wales, contested Holborn and St Pancras. Several parties operate in specific regions only. The main national parties, standing in most seats across all of the country, are listed below in order of the number of seats that they contested: • Conservative Party: The Conservative Party was the senior party in the 2010–15 coalition government, having won the most seats (306) at the 2010 election. The party stood in 647 seats (every seat except for two in Northern Ireland and the Speaker's seat). • Labour Party: Labour had been in power from 1997 to 2010. The party was Her Majesty's Most Loyal Opposition after the 2010 election, having won 258 seats. It stood in 631 constituencies, missing only the Speaker's seat, and all seats in Northern Ireland. • Liberal Democrats: The Liberal Democrats were the junior members of the 2010–15 coalition government, having won 57 seats. They contested 631 seats, and like Labour, only not contesting the Speaker's seat and all seats in Northern Ireland. • UK Independence Party (or UKIP): UKIP won the fourth most votes at the 2010 election, but failed to win any seats. They went into the election with two seats; due to having won two by-elections. They also won the most votes of any British party at the 2014 European election. It contested 624 seats across the United Kingdom. • Green Party: The Green Party went into the election with only one seat. However, they won the fourth-most votes in the 2014 European election. In 2010, Caroline Lucas became the party's first ever MP. In this election they received 3.8% of the vote. This made them the sixth largest party in terms of how many people voted for them. They stood in 573 seats. Minor parties Dozens of minor parties stood in this election. The Trade Unionist and Socialist Coalition stood 135 candidates and was the only minor party to have more than forty candidates. The Respect Party, who came into the election with one MP who was elected at the 2012 Bradford West by-election, stood four candidates. The British National Party, who finished fifth with 1.9% of the vote and stood 338 candidates at the 2010 general election, stood only eight candidates this year following a collapse in their support. They contested all 18 Northern Irish constituencies at the election. • Ulster Unionist Party (or the UUP): in 2010 the UUP entered an electoral alliance with the Conservative Party, and finished fourth in terms of votes in Northern Ireland, but won no seats. The party has one MEP, having placed third in the 2014 European elections. They came fourth in the 2011 Northern Ireland Assembly election. The UUP contested 15 of the 18 Northern Irish seats; the party did not run in two seats because of its electoral pact with the DUP, and also did not nominate a candidate against former party member, Sylvia Hermon. • Alliance Party of Northern Ireland: The Alliance Party had one MP going into this election, Naomi Long, who had been elected for the first time in 2010. They came fifth in the 2010 election by vote share. They have a relationship with the Liberal Democrats. However, Long sat on the opposition benches in the Commons and not with the Liberal Democrats on the government benches. The party contested all 18 Northern Irish constituencies in 2015. Smaller parties in Northern Ireland included the Traditional Unionist Voice, who won no seats at this election but had one member of the Northern Ireland Assembly, the Conservatives and UKIP (both are major parties in the rest of the UK, but are minor parties here). Scotland • Scottish National Party (or the SNP): The SNP only contested seats in Scotland and stood in all 59 Scottish constituencies. The party received the second most votes in Scotland and the sixth most overall in 2010, winning six seats. It won the 2011 election to the Scottish Parliament and had a surge of support since the Scottish independence referendum in September 2014, in which it was the main political party behind the losing Yes campaign. Most projections suggested that it would be the third-largest party overall after the 2015 election, in terms of seats won, overtaking the Liberal Democrats. Some UK political parties that only stand in part of the country have reciprocal relationships with parties standing in other parts of the country. These include: • Labour (in Great Britain) and SDLP (in Northern Ireland) • Liberal Democrats (in Great Britain) and Alliance (in Northern Ireland) • SNP (in Scotland) and Plaid Cymru (in Wales) • Plaid Cymru also recommended supporters in England to vote Green, while the SNP leader Nicola Sturgeon said she would vote for Plaid Cymru were she in Wales, and Green were she in England. However, Sturgeon also said that, if their candidate was the most progressive, she would vote for Labour were she in England. • Green Party of England and Wales (in England and Wales), Scottish Greens (in Scotland) and the Green Party in Northern Ireland (in Northern Ireland) On 17 March 2015 the Democratic Unionist Party and the Ulster Unionist Party agreed an election pact, whereby the DUP would not stand candidates in Fermanagh and South Tyrone (where Michelle Gildernew, the Sinn Féin candidate, won by only four votes in 2010) and in Newry and Armagh. In return the UUP would stand aside in Belfast East and Belfast North. The SDLP rejected a similar pact suggested by Sinn Féin to try to ensure that an agreed nationalist would win that constituency. The DUP also called on voters in Scotland to support whichever pro-Union candidate was best placed to beat the SNP. Candidates The deadline for parties and individuals to file candidate nomination papers to the acting returning officer (and the deadline for candidates to withdraw) was 4 p.m. on 9 April 2015. The total number of candidates was 3,971; the second-highest number in history, slightly down from the record 4,150 candidates at the last election in 2010. There were a record number of female candidates standing in terms of both absolute numbers and percentage of candidates: 1,020 (26.1%) in 2015, up from 854 (21.1%) in 2010. According to UCL's Parliamentary Candidates UK project the major parties had the following percentages of black and ethnic minority candidates: the Conservatives 11%, the Liberal Democrats 10%, Labour 9%, UKIP 6%, the Greens 4%. The average age of the candidates for the seven major parties was 45. The oldest candidate was Doris Osen, 84, of the Elderly Persons' Independent Party (EPIC), who contested Ilford North. and UKIP, were suspended from their respective parties after nominations were closed. Independent candidate Ronnie Carroll died after nominations were closed. ==Campaign==

By party Conservative In late 2014, six months before the election, the Conservatives decided to target Lib Dem seats as well as defending their own seats and targeting Conservative–Labour marginals, which ultimately contributed to their victory. In 2015 David Cameron launched the Conservative formal campaign in Chippenham on 30 March. Throughout the campaign the Conservatives played on fears of a Labour–SNP coalition following the Scottish independence referendum the year before. Labour The Labour campaign was launched on 27 March at Olympic Park in London. Ed Miliband's EdStone was a major feature of the campaign which was covered by the media. Deputy Leader of the Labour Party Harriet Harman embarked on a pink bus tour as part of her Woman to Woman campaign. Issues Constitutional affairs The Conservative manifesto committed to "a straight in-out referendum on our membership of the European Union by the end of 2017". Labour did not support this, but did commit to an EU membership referendum if any further powers were transferred to the European Union. The Lib Dems also supported the Labour position, but explicitly supported the UK's continuing membership of the EU. The election was the first following the 2014 Scottish independence referendum. None of the three major party manifestos supported a second referendum and the Conservative manifesto stated that "the question of Scotland's place in the United Kingdom is now settled". In the run-up to the election, David Cameron coined the phrase "Carlisle principle" for the idea that checks and balances are required to ensure that devolution to Scotland has no adverse effects on other parts of the United Kingdom. The phrase references a fear that Carlisle, being the English town closest to the Scottish border, could be affected economically by preferential tax rates in Scotland. Government finance The deficit, who was responsible for it and plans to deal with it were a major theme of the campaign. While some smaller parties opposed austerity, Possibility of a hung parliament Hung parliaments have been unusual in British political history since the Second World War, but as the outgoing Government were a coalition and opinion polls were not showing a large or consistent lead for any one party, it was widely expected and predicted throughout the election campaign that no party would gain an overall majority, which could have led to a new coalition or other arrangements such as confidence and supply agreements. This was also associated with a rise in multi-party politics, with increased support for UKIP, the SNP and the Greens. The question of what the different parties would do in the likely event of an inconclusive result dominated much of the campaign. Smaller parties focused on the power this would bring them in negotiations; Labour and the Conservatives both insisted that they were working towards winning overall majorities, while they were also reported to be preparing for the possibility of a second election later in the year. In practice, Labour were prepared to make a 'broad' offer to the Liberal Democrats in the event of a hung parliament. Most predictions saw Labour as having more potential support in parliament than the Conservatives, with several parties, notably the SNP, having committed to preventing a Conservative government. The Conservatives claimed a hung parliament with Labour as the largest party would result in a 'coalition of chaos', and David Cameron tweeted that the electoral choice was one between 'stable and strong government with me, or chaos with Ed Miliband'. Due to the substantial political turmoil in Britain in the years following the 2015 election, the tweet became infamous. The surprise Conservative victory was 'widely put down to the success of the anti-Labour/SNP warnings', according to the BBC and other media commentators. Labour, in reaction, produced ever stronger denials that they would cooperate with the SNP after the election. This was particularly notable for Labour, to whom the SNP had previously offered support: their manifesto stated that "the SNP will never put the Tories into power. Instead, if there is an anti-Tory majority after the election, we will offer to work with other parties to keep the Tories out". SNP leader Nicola Sturgeon later confirmed in the Scottish leaders' debate on STV that she was prepared to 'help make Ed Miliband prime minister'. However, on 26 April, Miliband ruled out a confidence and supply arrangement with the SNP too. Miliband's comments suggested to many that he was aiming to form a minority government. The Liberal Democrats said that they would talk first to whichever party won the most seats. They later campaigned on being a stabilising influence should either the Conservatives or Labour fall short of a majority, with the slogan 'We will bring a heart to a Conservative Government and a brain to a Labour one.' Both Labour and the Liberal Democrats ruled out coalitions with UKIP. Ruth Davidson, leader of the Scottish Conservatives, asked about a deal with UKIP in the Scottish leaders' debate, replied: 'No deals with UKIP.' She continued that her preference and the Prime Minister's preference in a hung parliament was for a minority Conservative government. UKIP said they could have supported a minority Conservative government through a confidence and supply arrangement in return for a referendum on EU membership before Christmas 2015. They also spoke of the DUP joining UKIP in this arrangement. UKIP and the DUP said they would work together in Parliament. The DUP welcomed the possibility of a hung parliament and the influence that this would bring them. Their leader, Peter Robinson, said that the DUP would talk first to whichever party wins the most seats. The DUP said they wanted, for their support, a commitment to 2% defence spending, a referendum on EU membership, and a reversal of the under-occupation penalty. They opposed the SNP being involved in government. The UUP also indicated that they would not work with the SNP if it wanted another independence referendum in Scotland. The Deputy Prime Minister and leader of the Liberal Democrats, Nick Clegg, warned against a potential 'Blukip' coalition (Conservatives, UKIP and by extension the DUP) with a spoof website highlighting imaginary policies from this prospective coalition, such as reinstating the death penalty, scrapping all benefits for under-25s and charging for hospital visits. Additionally, issues were raised about the continued existence of the BBC – as the DUP, UKIP and Conservatives had made a number of statements criticising the institution – as well as support for same-sex marriage. Plaid Cymru, the SNP, and the Green Party of England and Wales all ruled out working with the Conservatives, and agreed to work together 'wherever possible' to counter austerity. Each would also make it a condition of any agreement with Labour that Trident nuclear weapons were not replaced; the Green Party of England and Wales stated that 'austerity is a red line'. Both Plaid Cymru and the Green Party stated a preference for a confidence and supply arrangement with Labour, rather than a coalition. The leader of the SDLP, Alasdair McDonnell, said 'we will be the left-of-centre backbone of a Labour administration' and that 'the SDLP will categorically refuse to support David Cameron and the Conservative Party'. Sinn Féin reiterated their abstentionist stance. In the event, the Conservatives did, against expectations, secure a small overall majority, rendering most of the speculation and positioning moot. ==Television debates==

The first series of televised leaders' debates in the United Kingdom was held in the previous election. Returning major party leaders Cameron and Clegg participated, as did then-prime minister Gordon Brown, who did not seek re-election in his constituency in 2015. Following much debate and various proposals, a seven-way ITV debate with the leaders of Labour, the Conservatives, Liberal Democrats, UKIP, Greens, SNP and Plaid Cymru was held on 2 April. with a series of other debates involving some of the parties. A five-way BBC debate with the Labour, UKIP, Green, SNP and Plaid Cymru leaders was held on 16 April. The other parties criticised Cameron's absence from the debate. Finally, a Question Time special was broadcast on 30 April, featuring Cameron, Miliband and Clegg. Other party leaders – Sturgeon, Wood and Farage – were given about half an hour to answer questions from an audience in Ask ... programs. Ask Nicola Sturgeon, Ask Leanne Wood and Ask Nigel Farage were broadcast on BBC1 afterwards. ==Endorsements==

Various newspapers, organisations and individuals endorsed parties or individual candidates for the election. For example, the main national newspapers gave the following endorsements: National daily newspapers National Sunday newspapers ==Media coverage==

Despite speculation that 2015 would be the 'social media election', traditional media, particularly broadcast media, remained more influential than new digital platforms. Newspapers were next most influential, with the Daily Mail influencing people's opinions most (30%), followed by The Guardian (21%) and The Times (20%). There were concerns this 'meta-coverage' was pushing policy issues to the sideline. Policy received less than half of election news airtime across all five main TV broadcasters (BBC, ITV, Channel 4, Channel 5 and Sky) during the first five weeks of the campaign. focusing on the economy, tax, and constitutional matters (e.g. the possibility of a Labour-SNP coalition government), with the economy dominating the news every week of the campaign. Within reporting and comment about the economy, newspapers prioritised the Conservative Party's angles (i.e., spending cuts (1,351 articles), economic growth (921 articles), reducing the deficit (675 articles)) over Labour's (i.e., Zero-hour contracts (445 articles), mansion tax (339 articles), non-domicile status (322 articles)). Similarly, Steve Barnett, Professor of Communications at the University of Westminster, said that, while partisanship has always been part of British newspaper campaigning, in this election it was 'more relentless and more one-sided' in favour of the Conservatives and against Labour and the other parties. According to Bart Cammaerts of the Media and Communications Department at the London School of Economics, during the campaign 'almost all newspapers were extremely pro-Conservative and rabidly anti-Labour'. 57.5% of the daily newspapers backed the Conservatives, 11.7% Labour, 4.9% UKIP, and 1.4% backed a continuation of the incumbent Conservative – Liberal Democrat coalition government; 66% of Sunday national newspapers backed the Conservatives. Of newspaper front-page lead stories, the Conservatives received 80 positive splashes and 26 negative; Labour received 30 positive against 69 negative. Print media was hostile towards Labour at levels 'not seen since the 1992 general election', when Neil Kinnock was 'attacked hard and hit below the belt repeatedly'. Of the leader columns in The Sun, 95% were anti-Labour. and, at other times, called her a 'glamorous power-dressing imperatrix' and said that she 'would make Hillary Clinton look human'. The negative coverage of the SNP increased towards the end of the election campaign. Only ITV gave more airtime to Labour spokespeople (26.9% compared with 25.1% for the Conservatives). Airtime given to the two main political leaders, Cameron (22.4%) and Miliband (20.9%), was more balanced than that given to their parties. Smaller parties – especially the SNP – received unprecedented levels of media coverage because of speculation about a minority or coalition government. The five most prominent politicians were David Cameron (Con) (15% of TV and press appearances), Ed Miliband (Lab) (14.7%), Nick Clegg (Lib Dem) (6.5%), Nicola Sturgeon (SNP) (5.7%), and Nigel Farage (UKIP) (5.5%). However, according to analysts from Loughborough University Communication Research Centre: 'The big winners of the media coverage were the Conservatives. They gained the most quotation time, the most strident press support, and coverage focused on their favoured issues (the economy and taxation, rather than say the NHS).' Other than politicians, 'business sources' were the most frequently quoted in the media. On the other hand, trade union representatives, for example, received very little coverage, with business representatives receiving seven times more coverage than unions. Former prime minister Tony Blair was also in the top ten most prominent politicians (equal 9th), warning against the possibility of the UK leaving the EU. ==Opinion polling==

Throughout most of the 2010–15 Parliament, Labour held a consistent polling lead over the Conservatives. Labour overtook the Conservatives at the end of 2010 – benefiting from a collapse in Liberal Democrat support – holding a small lead throughout 2011. Following a brief tightening in early 2012, Labour opened up a wider lead as the Conservatives suffered a slump, partially due to rising UKIP support. UKIP passed the Liberal Democrats – whose ratings were still stagnant – as the third-placed party at the start of 2013. Following this, Labour's lead dipped a little as UKIP also gained support from them. Labour's lead gradually declined throughout 2014, largely attributed to increases in support for the SNP and the Green Party, as the Conservatives remained relatively level. Liberal Democrat support continued to fall, dipping into single-digits. UKIP won the most seats at the European elections in June 2014, receiving 26.6% of the vote. Though their support in the polls for Westminster never reached this level, it did rise up to over 15% through the year. The Scottish independence referendum was also held in 2014; despite the 'no' vote winning, support for the Scottish National Party rose quickly after the referendum. In Wales, where polls were less frequent, the decline in Labour's lead was smaller, while UKIP and Plaid Cymru made gains. Polling during the campaign itself remained relatively static, with the Labour and Conservative parties both polling between 33 and 34% and neither able to establish a consistent lead. Support for the Green Party and UKIP showed slight drops, while Liberal Democrat support slightly rose up to around 9%. In Scotland, support for the SNP continued to grow with polling figures in late March reaching 54%, with the Labour vote continuing to decline accordingly, while Labour retained their (reduced) lead in Wales. Projections one month before the vote The first-past-the-post system used in UK general elections means that the number of seats won is not exactly relative to vote share. Thus, several approaches were used to convert polling data and other information into seat predictions. The table below lists some of the predictions. Some predictions cover Northern Ireland, with its distinct political culture, while others do not. Parties are sorted by current number of seats in the House of Commons. Final projections before the vote Exit poll An exit poll, collected by Ipsos MORI and GfK on behalf of the BBC, ITN and Sky News, was published at 10 pm at the end of voting. It interviewed around 22,000 people across a sample of 133 constituencies: This predicted the Conservatives to be 10 seats short of an absolute majority, although with the 5 predicted Sinn Féin MPs not taking their seats, it was likely to be enough to govern – although Sinn Féin eventually only won 4 seats. The exit poll was markedly different from pre-election polls, which had been fairly consistent; this led many pundits and MPs to speculate that the exit poll was inaccurate, and that the final result would have the two main parties closer to each other. Former Liberal Democrat leader Paddy Ashdown vowed to "eat his hat" and former Labour "spin doctor" Alastair Campbell promised to "eat his kilt" if the exit poll was right. As it turned out, the results were even more favourable to the Conservatives than the poll predicted, with the Conservatives obtaining 330 seats, an absolute majority. Ashdown and Campbell were presented with hat- and kilt-shaped cakes (labelled "eat me") on BBC Question Time on 8 May. Survation also claimed that a poll they carried out a day before the election gave the Conservatives 37% and Labour 31%, though they said they did not release the poll (commissioned by the Daily Mirror) on the concern that it was too much of an outlier with other poll results. However, it was reported that pollsters had in fact picked up a very late swing to Labour immediately prior to polling day, not the Conservatives. It was reported after the election that private pollsters working for the two largest parties actually gathered more accurate results, with Labour's pollster James Morris claiming that the issue was largely to do with surveying technique. Morris claimed that telephone polls that immediately asked for voting intentions tended to get a high "Don't know" or anti-government reaction, whereas longer telephone conversations conducted by private polls that collected other information such as views on the leaders' performances placed voters in a much better mode to give their true voting intentions. Another theory was that 'shy Tories' did not want to openly declare their intention to vote Conservative to pollsters – this was the case in 1992, the last time pollsters significantly missed. A final theory was the 'Lazy Labour' factor, which claimed that Labour voters tend to not vote on polling day whereas Conservative voters have a much higher turnout. The British Polling Council announced an inquiry into the substantial variance between the opinion polls and the actual election result. The inquiry published preliminary findings in January 2016, concluding that "the ways in which polling samples are constructed was the primary cause of the polling miss". Their final report was published in March 2016. The British Election Study team suggested that weighting error appeared to be the cause. ==Results==

After all 650 constituencies had been declared, the results were: , mainly between the UKIP and Conservative Parties. Geographic voting distribution One result of the 2015 general election was that a different political party won the popular vote in each of the countries of the United Kingdom. This was reflected in terms of MPs elected: The Conservatives won in England with 319 MPs out of 533 constituencies, the SNP won in Scotland with 56 out of 59, Labour won in Wales with 25 out of 40, and the Democratic Unionist Party won in Northern Ireland with 8 out of 18. Outcome Despite most opinion polls predicting that the Conservatives and Labour were neck and neck, the Conservatives secured a surprise victory after having won a clear lead over their rivals and incumbent Prime Minister David Cameron was able to form a majority single-party government with a working majority of 12 (in practice increased to 15 due to Sinn Féin's four MPs' abstention). Thus the result bore resemblance to 1992. The Conservatives gained 38 seats while losing 10, all to Labour; Employment Minister Esther McVey, in Wirral West, was the most senior Conservative to lose her seat. Cameron became the first Prime Minister since Lord Salisbury in 1900 to increase his popular vote share after a full term, and is sometimes credited as being the only Prime Minister other than Margaret Thatcher (in 1983) to be re-elected with a greater number of seats for his party after a 'full term'. The Labour Party polled below expectations, winning 30.4% of the vote and 232 seats, 24 fewer than its previous result in 2010—even though in 222 constituencies there was a Conservative-to-Labour swing, as against 151 constituencies where there was a Labour-to-Conservative swing. Its net loss of seats were mainly a result of its resounding defeat in Scotland, where the Scottish National Party took 40 of Labour's 41 seats, unseating key politicians such as shadow Foreign Secretary Douglas Alexander and Scottish Labour leader Jim Murphy. Labour gained some seats in London and other major cities, but lost a further nine seats to the Conservatives, recording its lowest share of the seats since the 1987 general election. Ed Miliband subsequently tendered his resignation as Labour leader. The Scottish National Party had a stunning election, rising from just 6 seats to 56 – winning all but 3 of the constituencies in Scotland and securing 50% of the popular vote in Scotland. Winning just eight seats, the Liberal Democrats lost their position as the UK's third party and found themselves tied in fourth place with the Democratic Unionist Party of Northern Ireland in the House of Commons, with Nick Clegg being one of the few MPs from his party to retain his seat. The Liberal Democrats gained no seats, while losing 49 in the process—of them, 27 to the Conservatives, 12 to Labour, and 10 to the SNP. The party also lost their deposit in 341 seats, the same number as in every general election from 1979 to 2010 combined. The party lost all of their seats in the South West Region, a typical stronghold. It was the first time since 1966 (as the Liberal Party) that they won 0 seats in the Region. The UK Independence Party (UKIP) was only able to hold one of its two seats, Clacton, gaining no new ones despite increasing its vote share to 12.9% (the third-highest share overall). Party leader Nigel Farage, having failed to win the constituency of South Thanet, tendered his resignation, although this was rejected by his party's executive council and he stayed on as leader. In Northern Ireland, the Ulster Unionist Party returned to the Commons with two MPs after a five-year absence, gaining one seat from the Democratic Unionist Party and one from Sinn Féin, while the Alliance Party lost its only Commons seat to the DUP, despite an increase in total vote share.

Foreign reactions President Barack Obama of the United States congratulated Cameron and his Conservative Party on his "impressive electoral victory" and that he "looked forward to continuing to strengthen the bonds between our countries as we work together on behalf of global peace, security and prosperity." Resignations On 8 May, three party leaders announced their resignations within an hour of each other: Ed Miliband (Labour) and Nick Clegg (Liberal Democrat) resigned due to their parties' worse-than-expected results in the election, although both had been re-elected to their seats in Parliament. Nigel Farage (UKIP) offered his resignation because he had failed to be elected as MP for South Thanet, but said he might re-stand in the resulting leadership election. However, on 11 May, the UKIP executive rejected his resignation on the grounds that the election campaign had been "a great success", and Farage agreed to continue as party leader. Alan Sugar, a Labour peer in the House of Lords, also announced his resignation from the Labour Party for running what he perceived to be an anti-business campaign. In response to Labour's poor performance in Scotland, Scottish Labour leader Jim Murphy initially resisted calls for his resignation by other senior party members. Despite surviving a no-confidence vote by 17–14 from the party's national executive, Murphy announced he would step down as leader on or before 16 May. Financial markets Financial markets reacted positively to the result, with the pound sterling rising against the Euro and US dollar when the exit poll was published, and the FTSE 100 stock market index rising 2.3% on 8 May. The BBC reported: "Bank shares saw some of the biggest gains, on hopes that the sector will not see any further rises in levies. Shares in Lloyds Banking Group rose 5.75% while Barclays was 3.7% higher", adding: "Energy firms also saw their share prices rise, as Labour had wanted a price freeze and more powers for the energy regulator. British Gas owner Centrica rose 8.1% and SSE shares were up 5.3%." BBC economics editor Robert Peston noted: "To state the obvious, investors love the Tories' general election victory. There are a few reasons. One (no surprise here) is that Labour's threat of breaking up banks and imposing energy price caps has been lifted. Second is that investors have been discounting days and weeks of wrangling after polling day over who would form the government – and so they are semi-euphoric that we already know who's in charge. Third, many investors tend to be economically Conservative and instinctively Conservative." Electoral reform The disparity between the numbers of votes and the number of seats obtained by the smaller parties gave rise to increased calls for replacement of the 'first-past-the-post' voting system with a more proportional system. For example, UKIP had 3.9 million votes per seat, whereas SNP had just 26,000 votes per seat, about 150 times greater representation for each vote cast. UKIP stood in 10 times as many seats as the SNP. Noting that UKIP's 13% share of the overall votes cast had resulted in the election of just one MP, Nigel Farage argued that the UK's voting system needed reforming, saying: "Personally, I think the first-past-the-post system is bankrupt." Re-elected Green Party MP Caroline Lucas agreed, saying: "The political system in this country is broken [...] It's ever clearer tonight that the time for electoral reform is long overdue, and it's only proportional representation that will deliver a Parliament that is truly legitimate and better reflects the people it is meant to represent." Daily Telegraph investigation of abuse of Wikipedia Following the election, The Daily Telegraph detailed changes to Wikipedia pages made from computers with IP addresses inside Parliament raising suspicion that "MPs or their political parties deliberately hid information from the public online to make candidates appear more electable to voters" and a deliberate attempt to hide embarrassing information from the electorate. Telegraph Media Group fined On 21 December 2015, the UK Information Commissioner's Office fined the Telegraph Media Group £30,000 for sending 'hundreds of thousands of emails on the day of the general election urging readers to vote Conservative ... in a letter from Daily Telegraph editor Chris Evans, attached to the paper's usual morning e-bulletin'. The ICO concluded that subscribers had not expressed their consent to receive this kind of direct marketing. Election petition Four electors from Orkney and Shetland lodged an election petition on 29 May 2015 attempting to unseat Alistair Carmichael and force a by-election over what became known as 'Frenchgate'. The issue centred around the leaking of a memo from the Scotland Office about comments allegedly made by the French ambassador Sylvie Bermann about Nicola Sturgeon, claiming that Sturgeon had privately stated she would "rather see David Cameron remain as PM", in contrast to her publicly stated opposition to a Conservative government. The veracity of the memo was quickly denied by the French ambassador, French consul general and Sturgeon. At the time of the leak, Carmichael denied all knowledge of the leaking of the memo in a television interview with Channel 4 News. but after the election Carmichael accepted the contents of the memo were incorrect, admitted that he had lied, and that he had authorised the leaking of the inaccurate memo to the media after a Cabinet Office enquiry identified Carmichael's role in the leak. On 9 December, an Election Court decided that although he had told a "blatant lie" in a TV interview, it had not been proven beyond reasonable doubt that he had committed an "illegal practice" under the Representation of the People Act and he was allowed to retain his seat. Party election spending investigations At national party level, the Electoral Commission fined the three largest parties for breaches of spending regulations, levying the highest fines since its foundation: £20,000 for Labour in October 2016, £20,000 for the Liberal Democrats in December 2016, and £70,000 for the Conservative Party in March 2017. At constituency level, related alleged breaches of spending regulations led to 'unprecedented' On 2 June 2017, charges were brought under the Representation of the People Act 1983 against Craig Mackinlay, who was elected Conservative MP for South Thanet in 2015, his agent Nathan Gray, and a party activist, Marion Little. Appearing at Westminster Magistrates' Court on 4 July 2017, the three pleased not guilty and were released on unconditional bail pending an appearance at Southwark Crown Court on 1 August 2017. The investigation of Party Treasurer Simon Day remained ongoing. In 2016–18, the European Parliament found that UKIP had unlawfully spent over €173,000 of EU funding on the party's 2015 UK election campaign, via the Alliance for Direct Democracy in Europe and the affiliated Institute for Direct Democracy. The Parliament required the repayment of the mis-spent funds and denied the organisations some other funding. It also found that UKIP MEPs had unlawfully spent EU money on other assistance for national campaigning purposes during 2014–16 and docked their salaries to recoup the mis-spent funds. ==See also==
